 "summary": "Save chart state with spec_path, then export it with to_code or as PNG and SVG files.",
 "who": "A data scientist who explored visually and now needs the same charts in a report or pipeline.",
 "problem": "Charts made by clicking around are hard to reproduce or put under version control.",
 "outcome": "Saved chart configs plus Python code and image files you can commit and rerun.",
 "steps": [
  "Open the walker with a spec file: `walker = pyg.walk(df, spec_path=\"./chart_meta_0.json\")`",
  "Build your chart in the UI and click the save button",
  "Export the image with `walker.save_chart_to_file(\"Chart 1\", \"chart1.svg\", save_type=\"svg\")` or export_chart_png",
  "Get reproducible Python with `code = walker.to_code(dataset_name=\"df\")`",
  "Migrate older saved specs with pyg.spec.migrate before committing them"

 "agent_prompt": "With Kanaries/pygwalker, open <dataframe> with a spec_path, and once I have saved <chart name> in the UI, export it to SVG and PNG and generate the reproducible code with to_code. Put the code in <script file>.",
